40k for me too!

 

I just rolled over 60k and here's what I had done:

-Oil change w/ Royal Purple full synthetic
-new Fram oil filter
-added a can of Restore in with the oil change (4-cyl formula)
-new AC Delco iridium spark plugs
-contacted ARK and got all new exhaust gaskets for my cat-back
-flushed the radiator/new Dexcool
-had my front rotors (Powerslots) re-surfaced
-cleaned the throttle body
-front-end alignment performed (adjusted camber, caster, toe)
-topped off the washer fluid
-even out the air pressure in all 4 tires
-washed/claybarred/waxed it + extensive detailing

Mind you, the oil has been changed every 5k w/ Mobil-1 full synthetic (until I switched to Royal Purple), the AEM dryflow filter has been cleaned 3 times w/ the proper AEM dryflow filter cleaner, had my fuel filter replaced last summer at/around 50k, premium (93 grade) octane has always been used, and the car was HP Tuners tuned last summer, so I haven't had a CEL in ages. Really, the only "problem" I have with the car right now is my shocks/struts being very worn out, since the car has been lowered nearly the entire time I've owned it.

 

i heard something that engine restore isnt the best stuff to use? correct me if I am wrong

 

Another question: Why do I see 2 different hp ratings on the same car? What is it REALLY rated?

Ex: I was looking for the hp rating for my car (nowhere to dyno). I found one reputable site that said it had 148hp, and on here and other places, it says 145hp. Is the ecotec different than the L61 or are they the same? Yes, it's a dumb question, but you never know unless you ask, right?

 

Its just a lubricant that you add in with your oil that lines your cylinder walls and restores lost compression. I don't see how it could be of any harm to the engine.

 

A few things changed from year to year, that's why the hp and tq ratings are different...

 

i'm at like 65k+ and am thinking about going for a full tune up at the stealership just to check out everything, think its a good idea?? i know it will cost quite a bit but think it might be worth it with so many miles

 

Wow those are some serious miles guys. I hear bosch spark plugs are the best but I would still stick with the acdelco stockers. I changed my fuel filter at 17,000 and I believe thats what the manual said. It costs a hundred bucks but oh well.......

I'm thinking some new wiper blades and your good to go

 

You can order the fuel filter online for a lot less. I just ordered my silver mirror covers and the fuel filter from GMPD and paid $90 shipped for both items.

 

my fuel filter was 14.99, installed myself......100 bucks is just wrong.
